Item Síntese, determinação estrutural, análise dos orbitais naturais de ligação e estudo espectroscópico vibracional e eletrônico do composto de coordenação BIS (Dietilditiocarbamato) Ferro(II) [Fe(DDTC)2].(Universidade Brasil, 2023) Télles Zepeda, Claudio Andrés; Pessoa, Rodrigo SávioWe performed the synthesis, computational molecular modeling and vibrational/electronic spectroscopic analysis of the coordination complex Iron(II) Bis(Diethyldithiocarbamate) [Fe(DDTC)2]. The optimization of the molecular structure was performed using Density Functional Theory with the functional B3LYP and basis set 6-311G(d,p). The experimental FT-IR and Raman spectra of the complex were recorded in the range 4000 – 0 cm-1, in order to correlate them with the calculated spectra. Most of the DFT calculated frequencies were found to agree with the experimental results. In order to investigate the internal electronic mobility of the complex, we performed the natural bond orbital analysis (NBO), which provides information regarding intramolecular charge transfer interactions that result from the overlapping of bonding and antibonding orbitals, as well as information about the electronic distribution between the HOMO and LUMO orbitals due to charge transfers. We also correlated the calculated and experimental UV-Vis spectra in order to investigate the configurations of several excited states of the complex that involve intra-ligand transitions. The results corroborate the existence of several Ligand to Metal and and Metal to Ligand charge transfer transitions, as well as metal-centered d-d transitions.Item Uso da Ozonioterapia em fungos causadores de Onicomicoses: estudo in vitro(Universidade Brasil, 2024) Del Castilo, Denise Vivianni Ferreira; Assis, Lívia; Tim, Carla Roberta: Onychomycosis is a common fungal infection of the nails, predominantly caused by dermatophytes such as Trichophyton rubrum (T. rubrum) and Microsporum gypseum (M. gypseum) and is a notoriously difficult condition to treat. Thus, the objective of the present study was to evaluate and compare, in vitro, the effectiveness of different times of ozone therapy on the main fungi that cause onychomycosis. Dermatophyte fungi T. rubrum (ATCC 28188) and M. gypseum (ATCC 24102) were incubated at 28° C for 14 days. Subsequently, the fungi were divided into 9 experimental groups according to the experimental time: Control Group (CG): the fungi were cultivated and did not receive any treatment; Cultivated fungi and received ozone therapy for a time of 2 min (G2”); 4 min (G4”); 6 min (G6”); 8 min (G8”); 10 min (G10”); 12 min (G12”); 14 min (G14”) and 16 min (G16”). The ozone concentration used was 2 µg/mL, oxygen flow of 1/4 L/min and applied dosages of 157, 314, 451, 628, 785, 943, 1100 and 1257 mg/m2, respectively. The main results show that the use of topical ozone therapy was effective in reducing the germination percentage of T. rubrum and M. gypseum in all experimental periods, presenting complete eradication with a treatment time of 6 min for T. rubrum and 14 min for M. gypseum. In conclusion, ozone therapy used topically, with emphasis on the treatment time of 6 min for T. rubrum (628 mg/m2) and 14 min (1257 mg/m2) for M. gypseum, promoted antifungal action on the main dermatophytes responsible for critical complications of onychomycosis, and may be proposed as a adjuvant in dermatological treatments.Item Impacto do desassoreamento nos recursos hídricos de reservatório de importância socioturística em Fernandópolis-SP(Universidade Brasil, 2022) Ramos, Elise Baroni; Vanzela, Sergio; Menegasso, Cleber FernandoDesilting is an important work in reservoir’s recovery, however, even if temporary, it disturbs the environment and can become a process of potential pollution in water resources. The objective was to evaluate the silt excavation operation impact in an important sociotouristic reservoir in Fernandópolis-SP. For this purpose, qualitative water variables were monitored, and the evolution of the service was accompanied. Completely randomized experimental design in 2 x 3 x 4 factorial scheme was used, and the main effects were runoff periods (with and without runoff), the level of second were excavation periods (before, during and after) and the level of third were monitoring points (points upstream E1, E2 and E3 and point S downstream, in relation to the reservoir). 100 water samples were collected, in a total of 25 biweekly/monthly sampling campaigns, and 13 aerial drone surveys were carried out between July 2020 and March 2022. To evaluate the qualitative water variables, analysis of variance was performed for the analyzed effects, followed by the mean comparison test. To evaluate the excavation progress effect, the Pearson correlation test was performed, followed by regression analysis. It was observed that the dynamics of sediment removal presented two distinct periods, which terrain instability, associated with precipitated rainfall, reduced the operational yield by 59.6%. During the desilting work, there was negative impact in the ammonium and ammonia concentration, increasing the averages by 154.1% and 151.9%, respectively. The excavation dynamics correlated only with water conductivity, resulting in an expected average increment of 1 µScm-1 for every 175 m3 removed. Considering those results and the reservoir historical, landscape, cultural and tourist importance, the desilting operation was adequate. However, it is necessary to carry out restoration and maintenance works in the reservoir contribution basin to minimize future problems with siltation.Item Avaliação da descontaminação de máscaras de proteção facial utilizando radiação UV-C(Universidade Brasil, 2022) Mota, Mara Soares de Almeida; Navarro, Ricardo Scarparo; Baptista, AlessandraInfectious respiratory diseases (IRD) are predominantly transmitted by airborne droplets or aerosols between people with close interactions. IRDs have a high rate of mortality and transmission between populations. The use of face protection masks (FPM) are effective in reducing the transmission of IRDs. Different methods are used for surface decontamination. The physical method of decontamination with UV-C radiation has shown effective results in different areas. The aim of this in vitro study was to evaluate FPM decontamination using UV-C radiation. Quadrangular samples from the masks were contaminated with a suspension of 108 CFU/ml of E. coli, in exponential phase, with the aid of a spray bottle inside the laminar flow. Three types of masks were evaluated (n=9): Tricoline (cotton) (T), Surgical (S) and N95 (N) at different times of UV-C irradiation, with portable SURFACE UV® equipment (MMOptics, São Carlos, Brazil, ƛ= 254 nm), the distance of 1 cm from the surface of the samples, scanning mode, at times of 30s, 45s and 60 s. To evaluate the microbial reduction, the samples were immersed in a test tube containing sterile saline solution, submitted to mechanical agitation for microbial recovery, and subsequently performed serial dilutions in the order of 1:10. Aliquots of the suspensions were seeded on Mueller Hinton agar for final microbial counts. The experiment was carried out in triplicate. All data were analyzed for their distribution by the Shapiro-Wilk test. Parametric data were analyzed by ANOVA and Tukey test. Nonparametric data were analyzed using the Kruskal-Wallis and Wilcoxon test (p< 0.05). The study showed that UV-C radiation promoted effective decontamination of different models of FPM contaminated with E. coli. In Tricoline and Surgical the microbial reduction was observed in the time of 30 s and total decontamination in the times of 45 s and 60 s. In N95, total decontamination was observed at all irradiation times. The type of face protection mask influenced the effects of UV-C. The UV-C irradiation from 30 s onwards reduced the microbial load and from 45 s onwards promoted total decontamination in all types of masks tested.Item O IPTU verde no município de Jales/SP(Universidade Brasil, 2023) Celes, Natália Carolina Castanheira; Américo-Pinheiro, Juliana Heloísa PinêThe green IPTU is a tax that is levied on urban properties and makes up what is called the tax burden. It was implemented in the municipality of Jales/SP on November 11, 2009, to serve as a bonus for taxpayers, granting tax discounts to those who adopt certain sustainable practices provided for in Municipal Law No. 3,686/2009. Through this research, the Technical Manual for requesting Green IPTU in the municipality of Jales/SP was developed with the aim of covering all Urban Territorial Property Tax (IPTU) taxpayers in the municipality of Jales/SP, who seek a reduction in their burden. tax, as well as improving quality of life, minimizing environmental impacts. The purpose of the Manual is to inform the taxpayer what Green IPTU is about, what measures must be adopted to grant the discount, the advantages of this tax incentive and the procedure to be adopted to request the benefit. Its objective is to promote an incentive for owners to fulfill the social function of the property, benefiting society and the public sphere, through small ecological and environmentally friendly adaptations. To develop this work, a bibliographical review was carried out on IPTU, sustainability, municipal legislation and municipal data. The images and pictures used in the manual were created with the help of the CANVA website and artificial intelligence. The reduction in the value of IPTU is the main incentive to join the program, but the benefits of an ecological home extend to saving water and energy, which has a positive effect on the budget in the long term. It is concluded that the tax benefit presents both economic and environmental efficiency results.Item Inspeção de bovinos: prevalência de condenações em frigorífico SIE - Porto Velho / Rondônia(Universidade Brasil, 2024) Tenório, Tony Edgley Catão; Bertipaglia, Liandra Maria Abaker; Melo, Gabriel Maurício Peruca deThe work aimed to identify and document the main causes of head, tongue, foot, lips, liver, lung and heart condemnations of cattle in slaughterhouses under the State Inspection Service (SIE) in Porto Velho, Rondônia, as well as to determine the economic losses resulting from inadequate handling of the animal during pre-slaughter and failures related to the inexperience of the technician responsible. The research was carried out at the Areia Branca Frigorific, located in the Municipality of Porto Velho, in the State of Rondônia, through documentary analysis of official health inspection reports and official data referring to the condemnations of slaughtered cattle. The data were tabulated in an electronic spreadsheet and analyzed using descriptive statistics. The results showed that during the year 2023, there were several occurrences of injuries and convictions, with the highest incidences for the liver (3988 cases), caused by teleangiectasia, the lungs (11885 convictions), with the main cause being contamination and for the kidneys (19,443 convictions), of which 13,149 were due to contamination. There was a total of R$124,866.52 in economic losses, with the highest values relating to the liver with R$116,146.51 and the feet with a total of R$7,900.20. Therefore, it is concluded that it is extremely necessary to strictly implement hygiene, care and appropriate management measures that cover all phases of the slaughter process, in order to minimize and prevent contamination, the main reason for condemnations, as well as, carrying out training for everyone involved in the management of animals in the pre-slaughter phase, aiming to minimize financial losses, to provide quality products with lower losses.Item Desenvolvimento de plataforma digital para avaliar a ambiência em instalações de aves de produção(Universidade Brasil, 2024) Marini, Marina Tabalipa; Sgavioli, Sarah; Pereira, Luiz Arthur MaltaA importância da avaliação da ambiência em instalações de aves de produção é inegável na avicultura. Aves criadas fora da ambiência adequada podem sofrer queda de produtividade, comprometimento do bem-estar e problemas no desenvolvimento biológico dos sistemas. Portanto, é crucial mensurar, avaliar e qualificar a ambiência no interior dessas instalações para garantir o sucesso da avicultura. Este trabalho propôs a criação de uma plataforma acessível e prática para produtores rurais. Por meio da web (rede) usada em dispositivos como smartphones e tablets, os produtores podem acompanhar os cálculos dos índices de ambiência, verificar se os valores encontrados para os índices e variáveis bioclimáticas estão de acordo com o recomendado e identificar possíveis soluções para desvios encontrados. A plataforma fornece informações em tempo real, geradas por dispositivos instalados em galpões de aves de produção (frangos de corte, poedeiras comerciais e matrizes). Todo o software desenvolvido foi hospedado em um servidor web terceirizado. As funcionalidades administrativas da plataforma, que incluem gerenciamento de conteúdo e visualização de gráficos, entre outras, estão disponíveis para acesso no endereço eletrônico www.pmppa.com.br/aves. Essas funcionalidades podem ser acessadas de qualquer dispositivo com conexão à internet. Este trabalho possibilitou a avaliação, monitoramento e identificação de problemas relacionados à ambiência das instalações, além do armazenamento dos dados encontrados. Isso auxilia o produtor através de sugestões de ações sobre os manejos necessários para manter as aves na ambiência adequada.Item Parâmetros fisiológicos e desempenho de novilhas mestiças confinadas recebendo óleos essenciais na água de bebida(Universidade Brasil, 2024) Meira Filho, Wanderley Rocha; Dian, Paulo Henrique MouraThis study aimed to evaluate the physiological parameters (rectal temperature, respiratory rate, heart rate, and surface temperature of body regions) and performance (feed efficiency, feed conversion, and average daily gain) of crossbred ½ Angus x ½ Nelore heifers kept in feedlots and receiving eucalyptus and mint essential oils diluted in drinking water. The study was previously approved by the Ethics Committee for the Use of Animals (protocol 2200038). The experiment was conducted on a rural property associated with Universidade Brasil, in the municipality of Descalvado. Twelve animals, approximately 12 months old and weighing an average of 258,21±36,84 kg, were randomly distributed in individual covered stalls measuring 12m², with individual feeders and drinkers and a concrete floor, and divided into two treatments: T1 – drinking water with the addition of eucalyptus and mint essential oils at a concentration of 0.025%; T2 – drinking water without the addition of essential oils. The adaptation to the diet and facilities lasted 14 days. The experimental period was 36 days, with weighing on days 0, 18 and 36, totaling three weighings throughout the experiment. The diets were provided twice a day, at 7:00 am and 5:00 pm, and the diets were weighed individually, as well as the leftovers, for individual control of consumption. The water in the drinkers was changed daily, and consumption was controlled by measuring the water provided and the leftovers at the end of the day. During the weighings, rectal temperature, heart rate and respiratory rate were recorded. Daily thermographic images were obtained from the animals using the nasal mirror, side, chin and forehead, at 2:00 pm, at a distance of 1.5 m. The average climatic conditions were recorded and the temperature and humidity indexes (ITU) and black globe temperature and humidity (ITGU) were estimated. Water consumption was lower in animals that received essential oils in their drinking water compared to animals in the control group (p<0.05). The parameters of dry matter consumption, live weight, feed conversion, feed efficiency and average daily gain were not affected by the supply of essential oils (p≥0.05). The surface temperature of the side region, in the fifth week of the experimental period, was lower in heifers that received essential oils. The variables of surface temperature, rectal temperature, respiratory rate and heart rate of the animals did not differ between treatments. Supplementation of eucalyptus and mint based essential oils in drinking water showed promise in reducing water consumption and modulating surface temperature in specific areas of the animals, without compromising zootechnical performance parameters.Item Efeitos da suplementação com antioxidantes nos parâmetros hematológicos de bezerras lactentes da raça holandesa(Universidade Brasil, 2024) Moitinho, Aurélio Marcos dos Santos; Bertipaglia, Liandra Maria Abaker; Melo, Gabriel Maurício Peruca deCalf growth is challenged by environmental, sanitary, and nutritional stress, which exposes calves to oxidative stress and increases their susceptibility to diseases. Ensuring adequate sanitary and nutritional conditions is crucial for calves to overcome these challenges, develop good health, and become productive and long-lived animals. In this context, antioxidant supplementation emerges as a promising strategy to promote calf health and well-being. This study aimed to evaluate the effect of antioxidant supplementation on the hematological response of lactating Holstein female calves. Thirty calves were randomly divided into two groups: a supplemented group (received weekly oral supplementation with an antioxidant-based formulation) and a control group (received weekly oral supplementation with the same base formulation but without antioxidants). The experiment lasted 63 days with weekly supplementation. Blood samples were collected every 21 days during the experiment for complete blood count analysis. Oral supplementation with antioxidants demonstrated significant results in modulating hematological parameters. An increase in hematocrit, erythrocytes and hemoglobin compared to the control group. Furthermore, supplementation significantly increased leukocytes, especially lymphocytes, indicating improvement in the innate immune response. These findings suggest that antioxidant supplementation may be an effective strategy for improving hematological and immunological health in calves.Item Desenvolvimento de sistema de identificação individual e rastreabilidade de bovinos de corte por RFID(Universidade Brasil, 2024) Peres, Júlio Cesar Rocha; Soares, Vando Edésio; Pereira, Luiz Arthur MaltaThe objective of this research was to develop an individual identification and traceability system for beef cattle using RFID (Radio Frequency Identification). The research was conducted with a view to creating a user-friendly module, aiming at self service, in order to allow producers, regardless of their level of knowledge of technologies, to feel capable of entering the necessary information to ensure the traceability of the animals. An easy-to-use system was designed for users with different levels of familiarity with computers, using the PHP language, designed for web development and executed on the server. In addition to PHP, HTML, CSS, JavaScript and the Bootstrap framework were used, which facilitate the creation of responsive websites. The database structure was designed and created in MySQL, a relational database management system that allows the storage of various types of data. The results of the bibliographic review indicated that Brazil has reached a high level with the results of Brazilian livestock farming, with large investments that provide food safety and quality of meat for the Brazilian market. Likewise, the State of Rondônia has international health recognition status, as it has rigorously met the requirements and requirements of the foreign market, one of which is animal traceability, allowing for the identification of animals with greater security. During the development of the system, its efficiency was verified in all testing phases and its operation, with the platform's functionalities being validated using program-based testing, known as functional testing or black box testing. The system created was made available free of charge at the electronic address www.pmppa.com.br/rastreabilidade. Thus, it was concluded that the use of this system is relevant, as it aims to individually identify each animal belonging to the producers' herd and its entire history, with the primary focus being to ensure compliance with the required standards and health control.
